Questio de aqua et terra (37)

(37) Quod etiam sequatur ipsam substare omnibus corporibus, quod sequi etiam ex conclusione dicebatur, sic declaro: Potissima virtus potissime attingit finem, nam per hoc potissima est, quod citissime ac facillime finem consequi potest: potissima virtus gravitatis est in corpore potissime petente centrum, quod quidem est terra; ergo ipsa potissime attingit finem gravitatis, qui est centrum mundi; ergo substabit omnibus corporibus, si potissime petit centrum; quod erat secundo declarandum. (37) That it also follows that it must be below all other bodies (which was likewise declared to follow from our conclusion), I thus maintain: The most potent virtue most potently attains the goal; for what makes it most potent is, that it can most swiftly and easily reach the goal. The most potent virtue of gravity is in the body which most potently seeks the centre; and that body is earth. Therefore earth most potently approaches the goal of gravity, which is the centre of the world. Therefore it will be below all the other bodies, seeing that it seeks the centre most potently; which was the second point to be elaborated.
